Duke’s experienced neurosurgeons detect and treat arteriovenous malformations (AVM), abnormal connections between arteries and veins that can occur in the brain or spine.The vascular system defects, which range from a tangle of blood vessels to abnormal openings, can interfere with blood circulation and increase your risk of hemorrhage, seizure, and stroke. While AVMs are rare, our surgeons have the skill and experience needed to identify AVMs, monitor changes, and treat promptly to prevent or reduce your risk for serious complications.
AVM experience, expertise
We combine sophisticated imaging and extensive surgical experience to treat all types of blood vessel defects including arteriovenous malformations, cavernous malformation and dural spinal fistulas. abnormal openings that occur in the dura -- a leather-like cover over the brain and spinal cord. AVMs may require monitoring and treatment if they cause unhealthy pressure to build in the brain and spine. After identifing arteriovenous malformations, our experienced physicians use the latest advances to manage and repair AVMs that may increase your risk of serious complications.
Choose Duke for your AVM treatment because we offer:
- A leading referral center. We are a leading referral center because of our surgeon’s vast experience in managing and treating AVMs. Our team is also asked to provide a second opinion, and are often chosen to treat the AVM because of our vast expertise.
- Emergency care. When vessels weaken or rupture as the result of AVM, your potential for seizures, internal bleeding or stroke increases. Emergency surgery may be necessary. Our team of experienced neurosurgeons work quickly to restore blood flow in vital areas such as the brain or upper spine. We do our best to restore your full health.
- Surgical expertise in functional areas of the brain. We have extensive experience in successfully repairing arteriovenous malformations in parts of the brain that control key functions. We carefully map the brain before surgery and then wake the patient to test functionality during the procedure.
- Advanced imaging. We use tiny catheters and dye to create high resolution images of AVMs in a procedure known as angiography.
- Less invasive therapies. We are experts in minimally invasive and less invasive techniques that repair veins and arteries, reduce brain bleeding, and resume a healthy blood flow.
ARTERIOVENOUS MALFORMATIONS (AVM)
May be prescribed to treat symptoms including headache, back pain and seizures caused by AVMs.
Using a high magnification microscope and high resolution imaging, our surgeons remove AVMs and repair fistulas while minimizing damage to surrounding areas and neurological structures within the brain and spine.
Reroutes blood flow around blocked, narrowed or damaged arteries in the brain. Often essential in emergencies, a cerebral bypass may be required to restore healthy blood flow.
A catheter is inserted and equipped with coils to block the blood flow within the AVM, or plug the dural spinal fistula. This procedure may be done in combination with radiosurgery.
Computer imaging guides delivery of a single, high dose of radiation directly to the AVM. This procedure is typically used for AVMs that cannot be reached by surgery.
ARTERIOVENOUS MALFORMATIONS (AVM)
A catheter is inserted into a large artery and threaded through the circulatory system. A contrast agent is injected to capture images that allow neuroradiologists, specialists in the nerves found in the brain and spine, to view abnormal connections within arteries and veins and plan the appropriate treatment.
Specialized, 3-D images of the brain and its blood vessels are studied to analyze AVMs that may be at risk for bleeding or rupture.
Creates a map of brain activity to assess the risk of brain surgery and plan a surgical approach that minimizes impact and preserves function.
